WWE is currently working on a new entrance theme for Cesaro. While they specifically went with the no-music entrance because they felt it would be a good talking point, it was always supposed to be a short-term situation.
How long they'll go before they debut Cesaro's new entrance music is unknown, but it's definitely not meant to be a permanent or long-term solution.
Vickie Guerrero WWE Status
Vickie Guerrero is not gone from WWE, as of yet. She posted a message on Twitter over the weekend denying rumors that she had left the company.
A new report by The Wrestling Observer claims that Vickie Guerrero might still be on her way out, but it will be similar to Eve Torres' departure where she stayed on for a little while longer after giving notice.
Dean Ambrose Note
It's worth nothing that Dean Ambrose is ten days shy of becoming the longest WWE United States Champion since it actually became a WWE title. Ambrose has held the US title for 333 days, just 10 days less than MVP, who was the champion for 343 days.
Lex Luger is the longest title holder in the complete history of the United States Championship at 523 days between '89-90.
